Goal: 1 h. Hours use maker inverter efficiency where published, otherwise the 0.85 estimate, and leave out idle draw the maker doesn't publish. Stations shown out of stock or with availability not shown are skipped. How we pick.

A generic station of that rated size at the 0.85 default efficiency with no idle draw, assuming its watts are enough to run and start the load. Real stations are below.

Running and starting watts

  • Window AC (5,000 BTU), compressor running continuously: 525 W running, 1,050 W starting, 12,600 Wh a day (Champion wattage chart). Typical running W is the midpoint of the chart's 450–600W range.
  • Window AC (10,000 BTU), compressor running continuously: 1,050 W running, 2,100 W starting, 25,200 Wh a day (Champion wattage chart). Typical running W is the midpoint of the chart's 900–1,200W range.

These hours assume the compressor never cycles off, so a thermostat that cycles it gives more hours.
